The prime ob ect of my invention is to provide means electricallyoperated including a horn or a bell for warning a person passing'abuilding, such as a garage or small alley to the fact that an automobileis about to pass out of the opening of same.

A further object of the invention is to provide an electrically operatedsignaling system, which comprises a series of floor boards adapted to besupported on the floor of the garage at spaced intervals, the first ofsaid floor boards being positioned just inside of the doorway and .therest of the floor boards which constitute the series of same spaced atequal distances towards the rear of the garage and each of the floorboards'connected with a signal horn positioned at the opening of thebuilding, so that as the wheels of the automobile pass over the variousfloor boards, an electric circuit will be closed for operating thesignal horn to warn persons passing the front of the building that anautomobile is about to move out of same. The invention can alsobeadapted for. usein small alleys, whereas the building line extends outonto the side- 'walk ,and no warning is given to persons passing thealley that a vehicle is moving out of same.

A still further object of my invention is to provide an imfprovedelectrically operated v signal for use 0 garages, alleys, etc, which issimple in constructionand operation, durable, eflicient for theurposeintended. and one that can be manu actured and installed foroperation at a relatively low cost.

These and like objects of the invention will be better understood as thedescription follows and as is specifically pointed out in i and whichclearl illustrates the construction. and operation 0 my improvedsignaling ap paratus:

Figure 1 represents a perspective viewv of a garage showing theinvention applied to y 1n the-recess 3 Figure 2 is a diagrammatic viewof the ciriiuits 1 I d 1 h h igure is a ongitu ina section t roug onsetthe floor boards, showing the mannor of mounting same in the floor of agai 4 larged a t a igure is an en agmen ary en of one of the floorboards.

Referring to the accompanying drawingin detail, like characters will beused to des-- ignate like parts in the difierent'views.

In the drawing, the numeral 1 indicates the front of a garage, 2 theopening leading thereto, and the drive-way or floor of thegarage. v

Thepolice regulations of many cities require the drivers of anautomobile to sound their horns before Passing out of a. garage, but ina number 0 instances, the operator fails to comply with this regulation,which has resulted in considerable property loss and dams and also insome instancesflto the-loss 0 life, due to the machine striking personspassing the entrance to the garage. My invention has been designedprlmarily to provide improved signaling means for indicating the exit ofan automobile from the garage, regardless ofthe fact as to whether ornot the operator of the car sounds his born. In order to accomplish theabove, the

floor 3 is providedwith one or more longitudin al recesses 3' formed inthe surface of the floor and disposed at spaced intervals. The

floor boards or bars 4, are disposed in the supporting the latter on aplane slightly by the underabovethe floor of the garage. A contact point8 is carried side of each of the floor boards intermediate its ends anda lead wire 9 extends from the contact 8 to asignal born 10 which isposi tioned to ones1de of the opening leading into the garage. A secondcontact 11 is ieldably supported in a pocket 10' formed intermediate itsends directly beneath the contact 8 carried by each of the floor boards4, and a lead wire 12 connected to the contact 11" at one end and theopposite end to the born 10. Abattery 13 is positioned in the wire 9.

4 'companying' drawing, it can be readily, seen that when a machinestarts'to leave the garage, that the front wheels of same come incontact with the floor boards 4, thus forcing same downwardly andclosing contact points 8 and 11 and causing sounding of the horn 10. Assoon as the front wheels ofthe vehicle pass off ofthe floor boards 4,the springs 6 return same to the position indicated in Figure 3, thusbreaking the circuit, which is again closed by the rear wheels coming incontact with the floor boards 4. From the above it can be readily seenthat if three floor boards are employed in the signaling apparatus, thatthe machine coming from the rear of the garage and passing out of theentrance will close the circuit six different times, thus causing sixsoundings of the born 10 before the machine reaches the entrance 2.

In view of the foregoing description of my invention taken in connection.with the accompanying drawing, it is thought that any furtherexplanation as to the construction, operation and objects of myinvention are unnecessary.

While I have shown and described the preferred form of my invention, Irealize that various minor changes may be resorted to, withoutdepartingfrom the spirit and scope of the invention'as claimed, and therefore, Ido not wish to limit myself to the exact details of construction shown,nor-t0 the combination and arrangement of parts.

VVhat' I claim as new and desire to secure by Letters Patent is In acircuit closer for a device of the character described, the combinationwith a driveway having a longitudinal recess in the upper surfacethereof, said recess having a central and end pockets, of boltscentrally way, means for limiting the upward movement of the bar, a.terminal yieldably supported in said central cket of said recess, acontact carried by tii underside of said bar adapted to contact withsaid terminal when the bar is depressed and conductor wires leading fromsaid terminal and contact.

In testimony whereof, I have aflixed my signature.
